About

It's winter, it's snowy and it's cold. We are using the heating a lot. We checked the gas meter. At an expected price point of 0.38 euros, it seems that (current state - previous state) * price => (22868 - 21640) * 0.38 = 466.64 euros, on the 4th of December. That is a lot!

The plan is to cut costs by investing in isolation. Obvious problems seem to be the roof-windows leaking heat, windows leaking heat, poor adaptability to heat one room and let the other one stay cold.

Possibilities

Please add any suggestions you can think of below. Remember: the point is to cut cost. Not to end up with the most fancy isolation system in the western hemisphere.

PU-foam (selected)

Can be used to close all open-air gaps for the roof windows

Pros:

Easy to install

Cons:

Messy

Chemical

With lots of cans, becomes pricey

Price:

about 10 euros per can, we will need around 6

Status:

ongoing

Door between two rooms (selected)

Should help us only heating one room and letting the other one stay cold.

Pros:

We have already a door (thx Kurt)

Cons:

Takes some work to install it

Still need some wood and plugs to install it properly

Price:

Status:

Door installed

Temporary bubblewrap above

Locks down air movement well

Transparent plates

Buy see trough plates that are thick enough to trap some air (like double sided glass), and use them as a second layer to provide insulation.

Pros:

Will probably very effective

Lets sunlight in during day time

Cons:

Might be a bit more expensive

How to close the sides of the plates to prevent draft

Price:

?

"Theater" cloth

Get cloth just like the black one we already have in the back and seal off all roof windows.

Pros:

Will probably work reasonably

Will be cheap if we can get it for free

Easy to install and to seal

Cons:

We might not be able to get it for free to by

Might not work as well as we would like

Price:

?
